SEWING-MACHINE TABLE.

SPECIFICATION vforming part of Letters Patent No. 607,862, dated July 26, 1898. Application filed December 20,1897. Serial No. 662,726. (No model.)

To all whom it may concern:

Be it known that we, THEODOR KUNDTZ and ANDREW EIBEN, of Cleveland, Cuyahoga county, Ohio, have invented certain new and useful Improvements in Tables or Cabinets for Sewing-llIachines, dac.; and we do hereby declare the following to be a full, clear,and eX- act description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

Our invention relates to improvements in tables or cabinets for sewing-machines, dto.

The primary object of this invention is to provide novel and meritorious mechanism for actuating the tilting leaf that bears the sewing-machine head or other machine; and the invention consists in certain features of construction and combinations and arrangement of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure Iis a front side elevation of the upper portion of a table or cabinet embodying our invention, and in this figure portions are broken away and in section to more clearly show the construction. Fig. II is a rear side elevation of the same. Fig. III is an end elevation, mostly in vertical section, on line III III, Figs. Iand II. Fig. IV corresponds with Fig. III, eX- cept that in this figure the load-carrying leaf is in `its downwardly-tilted position and the mechanism instrumental Vin the elevation or actuation of the said leaf is in a corresponding position.

Referring to the drawings, A designates the top of the table or cabinet. TopAis provided centrally with a rectangular opening a, that extends through the top. A verticallytilting leaf B is arranged to enter and occupy the said opening and is horizontally hinged or pivoted at its forward end at B to and longitudinally of top A at the forward end of openinga. MemberB isknown as the loadbea-rin g leaf, that carries the sewin g-machine head or other machine, (not shown,) of the table or cabinet. Vhen the machine is not in use, leaf B isV tilted downwardly below top A, as shown in Fig. IV, and the said leaf is again tilted upwardly or elevated into opening a when the machine is required for use.

The said leaf B is operatively connected with the lifting leaf C, that is horizontallyhinged at one lend, as at C', to and transversely of the left-hand end of top A, and the arrangement of parts is such that when said leaf C v The cabinet or table at the rear is provided with a back A. Back A at its central p0r tion is provided with a vertical or upright slideway d. A slide D, vthat is composed, preferably, of wood, engages and is adapted to reciprocate endwise of (up and down) the said slideway. Slide D is provided with a forwardly-projecting arm d, that extends in under and transversely of the central portion of, the load-carrying leaf B. Arm d consists, preferably, of a metallic bar, that is rigidly and removably secured to slide D, preferably by means of screws d. Said arm d is provided at its rear end witha rearwardly-proj ecting and horizontally-arranged stud d2, that extends through the slide and through back A and is operatively connected at the outer or rear side of the said back with one end of a lever G, that has its opposite end pivoted horizontally to and transversely of leaf C, as at G-that is, one end of the said lever is operatively connected with leaf C, and the levers other end is mounted upon the aforesaid stud d2, and the lever at any suitable point between its ends and preferably near its central portion rests upon a roller II, that is suitably secured to the rear side of back A' and serves as a fulcrum for the lever. A

nut d5, mounted upon stud d2 at the outer side of the lever, prevents disconnection of the lever from the slide. Back A is suitably slotted, as at a2, to accommodate thelocation of the aforesaid stud during the descent and IOO 4 elevation of the slide.

VIO

The load-carrying leaf B is provided upon its under side at its rear end and central portion with a roller b, that rests upon arm d, and it is obvious that the said leaf is lowered or tilted upwardly according as the slide D and its lifting-arm are lowered or elevated. In Figs. I and III the said slide is' shown in its upper position, and in Fig. IV the slide is shown in its lower position. The arrangement of the operative connection between the said slide and leaf C is such that the slide and its arm d and the engaging load-carryin g leaf are in their elevated position when the said leaf C is in its open position, wherein it forms, as already indicated, an extension of the top of the table or cabinet, and the said slide and load-carrying leaf lower by gravity when the lifting leaf is tilted from its open position to the right and over the opening iu the aforesaid top. The trend of the lifting-lever'G is preferably such that the leverwill perform its function efliciently and easily. The slide-arm d at the forward side of and near the slide is provided with an upwardly and rearwardly extending incline d3, that has the arrangement required to render it capable of lifting roller Z7 and the connected leaf B into their eXtreme upper position, and the said arm at the rear of the said incline is provided with a rest d4, upon which the roller, and consequently the lifting leaf, have bearing when the said leaf is in its upwardly-tilted position.

Leaf B, when the same is in its upwardlytilted position, does not entirely close the rear portion of the opening a in the top ofthe table or cabinet, and the said rear portion of the` said opening is closed by a supplementary leaf b, that is arranged to enter and occupy the rear portion of the said opening at the rear of leaf B and is horizontally hinged or pivoted at its ends, as at b', to and longitudinally of top A. During the lowering of leaf B the supplementary leaf tilts downwardly by gravity, as shown in Fig. IV, and slide D at its forward side and forward of the back A' of the table or cabinet is provided with an upwardly-projecting member D', that has the arrangement required to render it capable during the elevation of the slide to enga-ge the aforesaid supplementary leaf and tilt the said leaf upwardly into the leafs horizontal position, wherein the said leaf, as already indicated, -closes the rear portion of the aforesaid opening a. The said arm D', to facilitate its operation of lifting leaf b, has a rearwardly and upwardly extending incline D3, arranged to engage the leaf when the latter is in its depending position at the junction of the forward edge and under side'of the leaf.

Leaf b is prevented in lowering from dropping into a perpendicular position by a shoulder A2, (see Fig. IV,) that is formed upon top A at the rear of the pivoted end of the leaf and arranged to form astop for arresting the downward movement of the leaf before the latter has dropped into a perpendicular position, so that the said leaf in its lower position inclines forwardly, and in the said position there is between the leaf and the adjacent portion of the top a space that is entered by the incline-bearing portion of the slide-arm D', and the said leaf is cutaway on its under side, as at 3, to accommodate the location of the incline-bearing portion of the aforesaid arm D' when the slide is in its elevated position. The load-carrying leaf B has its rear and free end rabbeted upon its under side, as at B3, and leaf b has its forward or free end rabbeted upon its upper side, as at b2, and the rabbeted end of leaf B rests upon the rabbeted end of leaf l) in the upwardly-tilted position of the said leaves, and consequently the arrangement of parts is such as to accommodate the rabbeted construction of the aforesaid leaves, and the slide-arm D' is extended forwardly, as at D2, and the said forward portion D2 of the arm extends in under and assists in supporting both of the aforesaid leaves in their elevated position.

The panel K, that is arranged to close the forward side of the space below the top of the table or cabinet when the load-carrying leaf is in its downwardly-tilted position, con'- stitutes a guard not only for the protection of the machine or mechanism (not shown) carried by the said leaf, but also improves the appearance of the table or cabinet. The said panel is horizontally hinged at its upper end, as at K', to the aforesaid top and is operatively connected at its lower end by means of a link K' with the arm CZ of the aforesaid slide, and the arrangement of parts is such that said panel is tilted rearwardly and upwardly when the said slide is actuated into its elevated position, and is lowered into a perpendicular position as shown in Fig. IV, when the slide and theload-carrying leaf are lowered.

What we claim is- 1. In a table or cabinet of the character indicated, the combination with the top A having an opening therethrough, the verticallytilting load-carrying leaf B hinged or pivoted to the forward portion of the said top horizontally and longitudinally of the cabinet and arranged to occupy the forward portion of the opening in the leafs upwardlytiltedposition, another leaf arranged to occupy therear or remaining portion of the opening and hinged or pivoted horizontally and longitudinally of the cabinet to the rear portion of the aforesaid top, and the lifting leaf C hinged horizontally and transversely of the cabinet at the tops left-hand end; of
